Abstract: This letter presents a millimeter‐wave ultra‐wideband compact Wilkinson power divider (WPD) with an impedance compensation technique. For the first time, parallel LC resonance networks are introduced to compensate for the rapidly decreasing real part of the input impedance, resulting in additional matching and lossless frequency points. Besides, this design also leads to a reduction in area by more than 25% compared to traditional lumped‐element WPDs. The proposed novel WPD is implemented using 65 nm CMOS technology with a compact core area of 0.022 mm2 (0.88 × 10−3 λ02) and achieves the measured insertion loss of 1.36‒1.56 dB from 62 to 104 GHz, reaching the 0.2 dB‐amplitude fraction bandwidth of 70% (42 GHz). Furthermore, the corresponding input‐output return loss and isolation are better than 10 and 17 dB, respectively. [ABSTRACT FROM AUTHOR]
